Hi All,
I have some weird problem. I have JMS client connecting to MQSeries5.3 on AIX. It transmitts and receives messages of all sizes. But when I tried to send message with size falling in range (32250 - 32650) bytes it gives the following exception after writing the message to the queue and when the process tries to disconnect.
linked exception: com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2009
java.lang.Exception: javax.jms.JMSException: MQJMS2000: failed to close MQ queue
On the server side the MQ shows
AMQ9208: Error on receive from host xxx.xx.xxx.xx.
EXPLANATION:
An error occurred receiving data from xxx.xx.xxx.xx over TCP/IP. This may be
due to a communications failure.
ACTION:
The return code from the TCP/IP (read) call was 73 (X'49'). Record these values
and tell the systems administrator.
Any ideas?....
Thanks in advance. |

If your patch level is under CSD 11 the best advice we can give you is to upgrade...

| We are on CSD12. I guess it is the latest fix available. |

Can you be more clear that you can easily send messages that are LARGER than that range?

Yes I can send messages larger than the range. Our message size is limited to 4 MB and I can send the messages of all sizes except that range.
When I send the message (in range) on the other end the message is received with few bytes as nulls at the end.
I tired even sending the message (in range) with the MQ API's but even they gave the same error. Below is error.
MQJE001: Completion Code 2, Reason 2009
MQJE001: An MQException occurred: Completion Code 2, Reason 2009

Here is the code which sends the message.
import javax.jms.JMSException;
import javax.jms.QueueConnection;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.Session;
import javax.jms.TextMessage;
public class MessageSender {
private MQConnection MQutil;
private QueueConnection connection = null;
private QueueSession session = null;
private QueueSender sender = null;
private TextMessage message;
/**
*
* @throws Exception
*/
public MessageSender() throws Exception {
this.MQutil = new MQConnection();
}
/**
*
* @param CLMmsg
* @param timestamp
* @return
* @throws Exception
*/
public String sendMessage(String CLMmsg, long timestamp) throws Exception {
try {
connect();
this.message = this.session.createTextMessage();
this.message.setJMSReplyTo(MQutil.getOUTQueue());
this.message.setText(CLMmsg);
this.message.setJMSTimestamp(timestamp);
this.sender.send(this.message);
disconnect();
} catch (JMSException e) {
Exception linkedExc = e.getLinkedException();
if (linkedExc != null) {
System.err.println("linked exception: " + linkedExc);
}
throw new Exception(e);
}
return this.message.getJMSMessageID();
}
/**
*
* @throws Exception
*/
public void connect() throws Exception {
this.connection = this.MQutil.getConnection();
this.session = this.connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
this.sender = this.session.createSender(this.MQutil.getINQueue());
}
/**
*
* @throws JMSException
*/
public void disconnect() throws JMSException {
this.sender.close();
this.session.close();
this.connection.close();
}
/**
*
* @return
* @throws Exception
*/
public String getCorrelationId() throws Exception {
return this.message.getJMSMessageID();
}

You should open a PMR.
Also, you're using "this" a lot, and I don't think it's necessary. maybe this is just a style point, but it looks ugly and confusing to me.

Note just to clarify, the important bit about the fixpack (csd) level is for the Java JARs, not the server side - I know you said you are at 12, but just validating that you are talking about the client side.
Are there any fdc;s on the server side. If you are at fixpack 12 with backlevel clients containing the problem I can think of, its quite possible for the channel to be terminated with an FDC. |

Here are the steps to trigger the error.
1. Make the targclient to MQ (in JNDI) for the sending queue
2. Send the message falling in 32227 - 32270 bytes range
It will through the error. |
